  • Trip mechanism
    Patent number: 4363363
    Abstract: A trip mechanism for a ground working tool and, particularly, for use on minimum tillage blade cultivators or mold board ploughs. A shank supports the ground working tool and is supported by the implement frame. A parallel-type deflection linkage allows deflection of the ground working tool with the position of the tillage tool remaining parallel to its original working position. A detent linkage keeps the tillage tool in its original position until the predetermined deflection force is reached.
